If you've not heard of Abalone, it's one of the most amazing - yet simple - board games in decades. It won "Game of the Decade" at the Cannes Games Festival 15 years ago, and has been a massive hit since its debut in 1990. The objective of Abalone is simple: push six of your opponent's marbles off of the board.

The rules of the game are very simple, and take only a few minutes to learn.
